It says:
This battery pack for PSP clips on the back of the PSP console and provides 1800mAh of extra power for your PSP console, allowing up to twice the battery life.
twice along with the original battery, or twice the juice of the original battery? Can anyone clarify me?
uhmm this is an external batery, its connected to the psp by the power conector, not by the battery slot... the original psp battery was already in his place...
1800 mAh is the same that the original battery capacity... then is twice along with the original battery
